Computer Telephony Integration
(CTI) Link
3
Release 5.0 and later systems support the use of an MLX port as a Computer
Telephony Integration (CTI) link on Hybrid/PBX mode systems. The CTI link
feature allows CTI applications to interact with the MERLIN LEGEND
Communications System over a local area network (LAN). The CTI link is the
system’s hardware and software interface to the Lucent Technologies
PassageWay Telephony Services product, which supports the Windows
®
95,
Windows NT, Windows 3.1, Windows 3.11 for Workgroups, Apple
®
Macintosh
®
OS and UNIX
®
systems platforms on the client side. CTI link circuitry connects to
an MLX port on the system and to a LAN server using Novell NetWare (releases
3.12, 4.1, and 4.11) or Windows NT 4.0 Server or Workstation software (Server is
recommended).
Programming a CTI Link
3
Before programming a CTI link, refer to the
Feature Reference
,
System Planning
,
and the documentation provided with the telephony platform.
The following constraints apply to programming an MLX port as a CTI link:
■
CTI links cannot be used with communications systems operating in Key
mode or Behind Switch mode.
■
CTI link extensions cannot be programmed on tip/ring or analog multiline
extension module ports. You must chose a free extension jack on an MLX
extension module. The free extension jack cannot be the first or fifth port
on an 008 MLX, 408 GS/LS-MLX, or 408 GS/LS-ID-MlX module; or the
first, fifth, ninth, or thirteenth port on an 016 MLX module (Release 7.0 and
later systems).
■
You cannot use a port reserved for an operator extension as the CTI link
extension.
■
You cannot use a system programming port as the CTI link extension.
■
You cannot program a port as a CTI link if it has a telephone or other
equipment connected to it.
■
MLX modules with firmware vintage 29 do not work correctly with the CTI
link. You must either choose a port on a board with firmware vintage that is
not 29 or replace the module with a module that has a firmware vintage
other than 29.
